Number 7 you divide 6.48 by 4
Hello!
Your answer would be 6
Than basically means switching the numbers
So basically if you were to multiply 6 x 6 (6 times less than)
You would get 36. Then subtract.
42 - 36 = 6, which is your answer.
I hope this helps!
Im one Brainliest away from next rank, so if possible please consider!
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.
cos x = BC / y
Solving for BC
BC = y cos x
BC is the distance between the Earth and the Sun :D
Answer:
cm/sec.
Step-by-step explanation:
We have been given that a particle in the first quadrant is moving along a path described by the equation 
such that at the moment its x-coordinate is 2, its y-coordinate is decreasing at a rate of 10 cm/sec. We are asked to find the rate at which x-coordinate is changing at that time.
First of all, we will find the y value, when 
by substituting in our given equation.
Since the particle is moving in the 1st quadrant, so the value of y will be positive that is 
.
Now, we will find the derivative of our given equation.
We have been given that , and 
.
Therefore, the x-coordinate is increasing at a rate of cm/sec.
1/2 4ab + 1/4 4ab
4.5ab + 4.25ab
